Poor service delivert. Nobody wants to take responsibility.

Hello Peter On 2017/11/17 I received a call from MTN Direct offering me a data package on promotion since I am a good paying customer. They offered me a data sim with 5G day and 5G night for R199 per month. With the promotion you get an extra 5 G day and 5 G night for the same price. So 10 G day and 10 G night for R199. As a extra bonus you get 30G that I can use for 3 months from the day the sim is activated. I accepted this offer and also took a R69 1G per month on another sim. The simcards was delivered at my home on 2017/11/23. I tried using the simcards but it was not active. I called them on the 27th and they activated the sims and promise within 24 hours data will be uploaded and available. The 28th still nothing. I phoned again and they gave me a different nr to call. I called that nr and they said the sims must be rica'd first. They assist me in that. Then they promised to upload data. On 2017/12/04 I phoned again as there was still no data. They gave me a different number to phone. I phoned the number and they said they will give the info through to the right people. They gave me a ref nr. On the 5th I received an sms that the problem was solved. I checked again but still no data uploaded. I started sending e-mails for assistance. On the 6th 5 G data was uploaded. Then I started enquiring about the 30G promotional offer. They told me they needed a contract to upload that data. I only received a invoice on the date of delivery as I have been a client with a contract for many years. I gave them all the info on the invoice and they promised to look into that. Then I received a different ref nr.after e-mailing them again. Up until now,today,2017/12/26, no response and no 30G data. It seems they dont want to take responsibility for this mess!!! I have to pay for a service that is useless.
